Belief in the basic tenet of "Work is Worship".

I have often heard many people say this, and to my mind, at least, it makes sense in an odd sort of way. How often have people missed their visit to a temple/mosque/dargah/church because they were busy at work? I think that while some people have unshakable faith in God/Allah/Ishwar, and will stop their work and first go and pray, the vast majority will willy-nilly skip the prayer, and either perform it later, or simply send up a prayer to be forgiven.

In Islam, prayer in the form of Salaat or Namaaz is mandatory, and as a Bohra, I am expected to pray three times a day. The timings of namaaz are strict, and follow the motions of the heavenly bodies, viz. the sun and the moon. During the afternoon prayers, and in the summer, during the evening prayers too, I am at my clinic and seeing patients. Even if I am not seeing patients, I find it very inconvenient to go for ablution and then the namaaz, as the clinic premises are too small for all this. Hence, most of the days, I skip the prayers.

Now, the crux is this: if I believe in the captioned tenet, then I am not doing anything wrong if I am busy @ work. Because, work is worship, right? And yet, unforgiving Islam will not accept this excuse and urge me to pray - either at the right time, or at least later on, when I am back home.

I am in a quandary. Should I accept the tenet, or embrace Islam unequivocally?
